Title: Improvements in or relating to freezing apparatus
Inventor: HIGHAM DAVID WALTER
IPC: F25D25/00
Filed: 1954-06-03
Abstract: 762,319. Refrigerators. HALL, Ltd., J. & E. June 3, 1955 [June 3, 1954], No. 16412/54. Class 29 A freezing compartment for articles such as fish &c. has a discharge door 10 and is partitioned by walls 6, 7, 8, preferably through which refrigerant or brine circulates, and which are movable by spring jacks 27, away from the frozen articles. For release of frozen articles from the compartment a wedge 45 breaks the ice bond between the door and the articles while movement of the walls 6, 7, 8 and hot gas defrosting breaks the bond with the walls of the compartment. The freezing compartment has two side walls 1, 2, of which wall 2 is freely hinged at its upper edge so that any increase in volume of the frozen articles is allowed for, and walls 5, fixed, 6, 7, 8, perpendicular to the side walls, through which refrigerant is circulated by the method described in Specification 758,285, forming compartments 18, 19, 20. Walls 6, 7, 8 are connected together on each side by strips 21, pivoted at one end to a rod 22 passing through brackets 23, fixed to wall 8, and having slots 25 in which slide bolts 24 attached to walls 6, 7, the lengths of the slots being such that walls 6 and 7 are out of phase with each other and with wall 8 when in motion. The discharge door 10, situated at the bottom of the freezing compartment, is pivoted by means of sleeves 11 on a shaft 12, with a delayed motion device, pins attached to the shaft 12 and elongated holes in the sleeves 11, allowing the shaft a limited angle of turn before it opens the door. The walls 6, 7, 8 are connected to the rod by spring jacks 27 joined to the shaft 12 by keyed links 30. Also keyed to shaft 12 is a rod 42 which passes through a bracket 47 on door 10 and carries a wedge 45 bearing against a horizontal frame member 46 and a shoulder 47 at the end of an angle iron stiffener 17 of door 10. The wall 2 carries secured at its lower free end an extension piece 48 located between two cams 49, 50 on shaft 12. To release articles from the freezing compartment shaft 12 is turned which without at first opening the door has the effect of driving wedge 45 between the shoulder 47 and frame member 46 breaking any ice bond between the door 10 and the articles; extension piece 48 is moved by cams 49, 50 breaking the ice bond with the wall 2 and links 30 are moved to a horizontal position compressing the jacks 27 since movement of walls 6, 7, 8 is not yet possible due to ice. Hot gas is circulated through the pipes in walls 6, 7, 8 and on sufficient melting of the ice the jacks 27 expand moving the walls 6, 7, 8 thus ensuring complete freeing of the frozen articles which fall through the now open door 10. The walls 6, 7, 8 may be hinged to move in a horizontal plane and the end walls 1, 2 and door 10 may be adapted for the circulation of'refrigerant.

Title: Purification of factor z derivable from antibiotic e.129
Inventor: ANSLOW WINSTON KENNAY
Filed: 1957-05-24
Abstract: Factor Z is isolated in pure form from crude antibiotic E129 (Specification 793,797), crude antibiotic PA 114 B and crude streptogramin (Specification 776,035) by extracting a solution of crude Factor Z in a water-immiscible or at least partially water-immiscible organic solvent therefor with an aqueous acidic solution and recovering the Factor Z from the aqueous extract. The organic solvent may be (a) a good solvent, i.e. dissolves more than 5% Factor Z, e.g. methyl ethyl ketone, acetophenone, chloroform, methylene chloride and n-butanol; (b) an intermediate solvent i.e. dissolves 0.5 to 5% Factor Z, e.g. ethyl acetate, isopropyl acetate, ethyl propionate and methyl isobutylketone, or an aromatic hydrocarbon such as toluene; and (c) a poor solvent i.e. dissolves less than 0.5% of Factor Z e.g. an aliphatic hydrocarbon such as hexane, diethyl ether and di-isopropyl ether. Preferably the good solvent is used in admixture with an intermediate or a poor solvent. The aqueous acid may be a mineral acid e.g. hydrochloric, sulphuric or phosphoric or an organic acid such as toluene sulphonic and oxalic acids.  N2 to N10 acid is preferred.  It is preferred to separate Factor A from the crude Factor Z by fractional crystallization from e.g. ethyl acetate or methyl isobutyl ketone prior to the acid purification step.  Coloured impurities may also be removed by treating solvent extracts of crude Factor B with aqueous alkali of r H 10 to 12 preferably containing a water-miscible organic solvent. Purified Factor Z is recovered from the acid extract by extraction with a good or intermediate solvent, or a mixture thereof, preferably after neutralization to r H 6.5. Specifications 799,053 and 820,658 also are referred to.

Title: Improvements in or relating to the manufacture of preparations for the treatment of the skin
IPC: A61K35/36
Filed: 1931-06-08
Abstract: Preparations for the medical or cosmetic treatment of the skin are obtained by extracting the skin of a warm-blooded animal with a lipoid solvent such as ether, removing the solvent from the extract by evaporation and incorporating the residue of the extract with a suitable excipient in the form of a lotion, cream, or ointment, or emulsifying it in water with the aid of soap or other emulsifying agent.  According to an example an ether extract is made from the skin of a young pig, subcutaneous fat having been removed previously and the skin, unless treated immediately after slaughter, having been steeped in dilute ammonium carbonate solution to prevent autolysis. The residue after evaporation of the ether is either triturated directly with an excipient to obtain an unguent to be worked up to a cream, or is treated with a dilute aqueous solution of sodium carbonate, containing a little antiseptic such as chloreton or tricresol, so as to obtain an emulsion to be added to an excipient.

Abstract: 821,084. Stuffing-box substitutes. GASKELL & CHAMBERS Ltd., [trading as NON-DRIP MEASURE CO.]. May 2, 1958 [May 31, 1957], No. 17408/57. Class 122 (5). A seal between the shaft 12 and the housing 1, 1a of a centrifugal pump comprises a disc 16 of synthetic rubber, plastic or like material held in a fluid-tight manner in the housing and provided with a central aperture which engages in a groove 15 formed in the shaft or in a sleeve 14 secured thereon. As shown, the outer periphery of the disc, which may be of Neoprene, is mounted in a recess 1b of larger diameter than the disc and is clamped between a spacer 4 and the housing 1, 1a the disc being located radially by the close fit of the central aperture with the groove 15; the recess 1b may, alternatively, be formed in the spacer 4. In operation, the flexible central portion of the disc 16 permits axial floating movement of the shaft which thereby causes one or other of the side walls of the groove 15 to be forced into sealing contact with the disc. The sealing effect may be increased by providing a number of holes 17 in the impeller 9 of the pump which suck the pumped liquid between the disc and the impeller back into the latter, thereby maintaining a lower pressure on the pump side of the disc. Due to the bedding-in of the disc with the walls of the groove the close fit produced thereby maintains the sealing effect when the shaft is stationary. A liquid-finger 18 and drain hole 19 are also provided on the motor side of the disc.
